    • Bustamante Franco, Sebastián Felipe (Universidad de Chile, 2018)
      The main focus of this thesis is the study of monochromatic cycle partitions in uniform hypergraphs. The first part deals with Berge-cycles. Extending a result of Rado to hypergraphs, we prove that for all $r,k \in \N$ ...

      The mechanism by which homocysteine (Hcy) causes endothelial dysfunction is probably mediated by oxidative stress. The aim of this study was to evaluate the effect of oxidative stress on endothelial function in young and ...
    • Rojas, Cecilia V.; Neely, Alan; Velasco-Loyden, Gabriela; Palma, Veronica; Kukuljan Padilla, Manuel (1999)
      Mutations in the human skeletal muscle Na+ channel underlie the autosomal dominant disease hyperkalemic periodic paralysis (HPP). Muscle fibers from affected individuals exhibit sustained Na+ currents thought to depolarize ...
    • Bravo Silva, Jaime (Centro de Estudios Académicos en Neuropsicología, 2016)
      There is an urgent need to increase the Joint Hypermobility Syndrome (JHS) awareness, that for most authors is the same as the Ehlers-Danlos Hypermobility type (formerly called EDS type III) that is a congenital, very ...
    • Pan, Li; Pezzuti, Todd; Lu, Wei; Pechmann, Cornelia (Elsevier Inc., 2019)
      The effects of hyperopia and frugality on spending have not been directly compared. Moreover, previous research on hyperopia has focused on the avoidance of luxury spending, rather than spending on routine consumer goods. ...
    • Eisner, Verónica; Quiroga, Clara; Criollo Céspedes, Alfredo; Eltit Ortega, José Miguel; Chiong Lay, Mario; Parra, Valentina; Hidalgo, Karla; Toro, Barbra; Díaz Araya, Guillermo; Lavandero González, Sergio (ELSEVIER, 2006-06-12)
      NF kappa B is a participant in the process whereby cells adapt to stress. We have evaluated the activation of NF kappa B pathway by hyperosmotic stress in cultured cardiomyocytes and its role in the activation of caspase ...

      NFκB is a participant in the process whereby cells adapt to stress. We have evaluated the activation of NFκB pathway by hyperosmotic stress in cultured cardiomyocytes and its role in the activation of caspase and cell ...
    • Peña Oyarzún, Daniel; Troncoso Cotal, Rodrigo; Kretschmar, Catalina; Hernando, Cecilia; Budini, Mauricio; Morselli, Eugenia; Lavandero González, Sergio; Criollo Céspedes, Alfredo (Impact Journals, 2017)
      Various intracellular mechanisms are activated in response to stress, leading to adaptation or death. Autophagy, an intracellular process that promotes lysosomal degradation of proteins, is an adaptive response to several ...
    • Eisner, Verónica; Criollo Céspedes, Alfredo; Quiroga, Clara; Olea Azar, Claudio; Santibáñez, Juan Francisco; Troncoso, Rodrigo; Chiong Lay, Mario; Díaz Araya, Guillermo; Foncea, Rocío; Lavandero González, Sergio (ELSEVIER, 2006-08-07)
      We have recently shown that hyperosmotic stress activates p65/RelB NF kappa B in cultured cardiomyocytes with dichotomic actions on caspase activation and cell death. It remains unexplored how NFKB is regulated in cultured ...

    • Serrano Contreras, Patricio; Generini, Gladys; Michelsen, Harold; Pumarino, Hugo; Campino, Carmen (1981)
      Although hyperprolactinemia and galactorrhea occur in primary hypothyroidism, factors influencing their presence are not well established. To further define these factors, the duration of illness and serum levels of PRL ...
    • Garaba Shungudzemwoyo, P.; Acuña Ruz, Tomás; Mattar B., Cristián (Copernicus Gesellschaft MBH, 2020)
      Remote sensing of litter is foreseen to become an important source of additional information relevant to scientific awareness about plastic pollution. Here, we document directional hemispherical reflectance measurements ...
    • Sánchez Ilabaca, Jaime; Lumbreras, Mauricio (2014-01-09)
      We introduce a conceptual model for building interactive hypermedia literary stories. Hyperstories extend and plasticize the idea of «branching games» and the classic «choose your own adventure» stories. The model combines ...
    • Escobar, S. (2002)
      The association of hypertension and coronary heart disease is a frequent one. There are several pathophysiologic mechanisms which link both diseases. Hypertension induces endothelial dysfunction, exacerbates the atherosclerotic ...
    • Pereira, Ana; Garmendia, Maria Luisa; Alvarado, Maria Elena; Albala Brevis, Cecilia (Asian Pacific Organization for Cancer Prevention, 2012)

      Prenatally malnourished rats develop hypertension in adulthood, in part through increased alpha(1)-adrenoceptor-mediated outflow from the paraventricular nucleus (PVN) to the sympathetic system. We studied whether both ...
    • Amigo, N.; Loyola, C.; Davis, Sergio; Gutiérrez, G. (Elsevier, 2013)
      An atomic-level simulation of the collisions between a nano-projectile against a target, both composed of copper, is presented. The study is performed by means of molecular dynamics simulations, in a system at a temperature ...
